Not that I read every column, but it was interesting from time-to-time.
Today, I have my own Household Hint.
My bachelor apartment has a regular apartment-sized refrigerator. To keep the inside clean, I use cardboard flats on each shelf. By wonderful coincidence, if I buy a full case of Equate Weight Loss Shakes, two flats fit perfectly on each shelf. Six flats in all.
They soak up any spills, and are easily replaceable.
My flats are a PERFECT 11 x 16 1/2 inches. You may have to experiment to get the right size, but it will be worth it in the long run.
No fuss. No mess.
